Description

Technical Field

[0001] This utility model relates to the field of kitchen cleaning equipment technology, specifically a household chopsticks washing machine. Background Technology

[0002] With the fast pace of life and increased awareness of household hygiene, the cleaning methods for chopsticks and other tableware are gradually gaining attention. Currently, there are two main ways to clean chopsticks in the home: one is to wipe each chopstick individually with a cleaning cloth or sponge, and the other is to hold several chopsticks in your hands and rub them back and forth to remove surface stains.

[0003] While wiping with a cleaning cloth can achieve some cleaning, it is inefficient when dealing with large quantities, and the cloth can easily breed bacteria after repeated use, posing a risk of cross-contamination. Washing by hand is simple, but the smooth and slender shape of chopsticks causes them to collide randomly, producing noise, damaging the paint, and even leading to fuzzing or breakage. Furthermore, the friction contact area during washing is limited, resulting in uneven cleaning, and the cleaning effect is poor when oil stains are heavy. There are also risks of slipping, wetting clothes, or accidentally injuring hands.

[0004] Relying on the above methods to clean chopsticks in the long term not only fails to meet the family's needs for efficient, even, and hygienic cleaning, but also results in a poor cleaning experience, high labor intensity, and difficulty in guaranteeing the safety and appearance integrity of the cleaned tableware.

[0005] In view of the above problems, a household chopsticks washing machine is proposed. Utility Model Content

Detailed Implementation

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Please see Figure 1-18This utility model provides a technical solution: a household chopsticks washing machine, including a fixing mechanism 1, and an internal support mechanism 2 is assembled inside the fixing mechanism 1; The fixing mechanism 1 includes a base 11, a motor 12 is mounted at the center of the base 11, a coupling 15 is mounted at the output end of the motor, a shaft 18 is inserted into the outside of the coupling 15, an outer fixing cylinder 111 is mounted on the outside of the base 11, and a fixing cotton 115 is fixed on the inside of the base 11. At least two fixing members 21 are fixedly mounted on the outside of the insert shaft 18. Each fixing member 21 is provided with a sliding member 22 at equal intervals in the coaxial direction. The sliding member 22 is slidably mounted on the outside of the insert shaft 18. A connecting rod 28 is mounted between the two sliding members 22. Several sets of hinge arms 23 are hinged to the outside of the fixing member 21 and the sliding member 22. A support plate 25 is rotatably mounted at the hinge point of the hinge arm 23. An elastic cotton 26 with elasticity is sleeved on the outside of the support plate 25. When not powered on, the insert shaft 18 is stationary. The sliding member 22 extends towards the fixed member 21 under the action of the spring 27, causing the hinge arm 23 to retract, which in turn drives the support plate 25 to retract as a whole. The elastic cotton 26 is compressed and wrapped around the insert shaft 18, forming a central cavity area. The user can insert several chopsticks into the gap between the elastic cotton 26 and the fixed cotton 115, and pour an appropriate amount of water and detergent into the gap to form a structure to be cleaned.

[0040] After loading, the user places the connecting cover 110 onto the outer fixing cylinder 111 and presses down on the pressing structure at the top of the insert shaft 18 using the pressure rod 29, completing the closure of the control system (described later). This starts the motor 12 and drives the insert shaft 18 to rotate at high speed via the coupling 15. During the rotation of the insert shaft 18, since the sliding member 22 and the insert shaft are in sliding fit, the rotation does not hinder the sliding action. At the same time, the downward pressing action of the pressure rod 29 causes the sliding member 22 to move downward away from the fixing member 21, overcoming the elastic force of the spring 27 and compressing the spring. The movement of the sliding member 22 pulls the connecting rod 28 to unfold the hinge arm 23, and then unfolds the support plate 25, causing the elastic cotton 26, which was originally contracted around the insert shaft, to be stretched open, forming a wrapping structure that fits tightly against the outer wall of the chopsticks.

[0041] In this state, the elastic cotton 26 and the fixed cotton 115 are respectively attached to different surfaces of the chopsticks. As the motor drives the insertion shaft to rotate, the center of the insertion shaft drives the chopsticks to rotate, while the elastic cotton 26 and the fixed cotton 115 remain relatively stationary or swing in opposite directions at low speed, thereby generating relative frictional cleaning force to effectively remove residual stains from the surface of the chopsticks.

[0042] Specifically, a threaded tube is provided above the middle of the base 11, and a connecting tube 13 is screwed to the outside of the threaded tube. A motor mounting bracket 14 is fixed at the center of the threaded tube, and the motor 12 is fixed to the motor mounting bracket 14 by screws. The motor mounting bracket 14 has an annular sleeve structure and is made of high-strength, corrosion-resistant material. Its lower end is firmly connected to the threaded tube in the middle of the base 11 via threads. This effectively prevents the motor from shifting due to vibration during use and also provides a certain degree of ease of disassembly and assembly. The motor 12 is connected to the mounting bracket 14 via multi-point screws to avoid eccentric operation caused by high-speed rotation, thereby improving the stability and coaxial accuracy of the shaft 18.

[0043] The connecting pipe 13 not only provides external protection but also, through its tight connection with the threaded pipe, achieves a seal around the internal motor mounting structure, effectively preventing moisture from entering the motor compartment. This structure combines mechanical stability with protective sealing, ensuring the equipment's reliability during long-term operation.

[0044] Specifically, a waterproof cover 17 is screwed to the top of the connecting pipe 13. A bearing is provided on the inner side of the waterproof cover 17. The inner side of the bearing is fitted to the outside of the insert shaft 18. Waterproof components are provided at the threaded connection between the waterproof cover 17 and the connecting pipe 13 and at the connection between the waterproof cover 17 and the insert shaft 18. The waterproof cover 17 is made of high-toughness plastic or stainless steel, and its bottom inner edge has a groove for installing a sealing rubber ring or silicone ring, forming the first waterproof sealing surface at the threaded connection with the connecting pipe 13. When the insert shaft 18 passes through the waterproof cover 17, a double-layer sealing ring is also provided in the axial interference fit area to form a second sealing barrier to prevent cleaning fluid, foam or steam from seeping into the motor compartment along the axial gap.

[0045] The bearing structure stabilizes the rotation path of the insert shaft 18. It is interference-fitted with the insert shaft 18 and fixed to the inner wall of the waterproof cover 17 by a retaining groove, so that the insert shaft can maintain good circumferential coaxiality when running at high speed. Since the waterproof cover 17 and the connecting pipe 13 adopt a threaded locking structure, disassembly and assembly are convenient, and users can perform maintenance and replacement after long-term use, thereby ensuring the protective reliability of the whole machine.

[0046] Specifically, the bottom surface of the base 11 is provided with a hollow opening, and the top of the base 11 is integrally formed with a fixing ring 113. The outside of the fixing ring 113 is fixed with a snap-fit ​​cylinder 114 by a snap-fit ​​claw 116, and the fixing cotton 115 is sleeved on the inner wall of the snap-fit ​​cylinder. The hollow opening is located at the center of the bottom surface of the base 11, and its shape matches the bottom structure of the snap-fit ​​cylinder 114, making it easy to insert, remove, and replace. The snap-fit ​​cylinder 114 is a hollow cylindrical structure with snap-fit ​​grooves on its outer wall corresponding to the snap-fit ​​claws 116. During installation, it can quickly form a stable connection with the fixing ring 113 by pressing down and rotating.

[0047] To enhance ease of use and equipment stability, the base 11 is symmetrically equipped with several support feet around its bottom, preferably made of rubber anti-slip pads. The height of these feet is slightly higher than the bottom edge of the openwork, ensuring that the openwork does not directly contact the table surface when the equipment is placed on a flat surface. This creates a collection space that can hold water droplets, foam, or residue, facilitating ventilation and dehumidification, as well as allowing users to regularly wipe or drain wastewater.

[0048] The fixing cotton 115 has a detachable structure and is installed by being limited by the inner wall of the snap-fit ​​cylinder 114. Its material is a porous sponge or fiber cotton with strong adsorption and washability, providing stable clamping force and assisting in adsorbing some impurities during washing. For disassembly and replacement, the user only needs to disconnect the snap-fit ​​cylinder 114 from the fixing ring 113 to remove the snap-fit ​​cylinder and the internal fixing cotton 115 as a whole, making the operation convenient.

[0049] Specifically, the outer walls of the fixing member 21 and the sliding member 22 are provided with hinge claws in the circumferential direction. The outer side of the hinge claw is hinged to one end of the hinge arm 23. The other ends of the two hinge arms 23 of the single set of fixing member 21 and sliding member 22 are hinged to each other, and the hinge arms that are hinged to each other are hinged to the outside of the hinge head 24. The fixing head 24 is integrally formed on the inner wall of the support plate 25. This utility model preferably adopts a structure with two sets or two groups of symmetrically arranged fixing members 21 and sliding members 22. On the one hand, it can ensure that the outward expansion direction of the support plate 25 and elastic cotton 26 is uniform and symmetrical under the rotation drive of the insertion shaft 18, avoiding low cleaning efficiency caused by eccentric force or uneven contact on one side. On the other hand, through the coordinated unfolding of the double sets of connecting rods 28 and hinged arms 23, a complete cleaning circumference structure around the insertion shaft 18 can be formed, which can adapt to the cleaning needs of inserting multiple chopsticks at the same time and increase the loading capacity.

[0050] Preferably, in the two sets of hinge arms 23, the hinge arm at the bottom is slightly longer than the hinge arm at the top. This ensures that during the downward movement of the slider 22, which unfolds the entire inner support mechanism, the angle of the bottom support plate 25 is slightly greater than the unfolding angle of the upper support plate 25. Consequently, the elastic cotton 26 forms an inwardly tapered conical profile after unfolding. This structure is particularly suitable for everyday household chopsticks that are thinner at the top and thicker at the bottom, achieving a closer fit for cleaning and further enhancing the frictional removal of surface stains, thus significantly improving cleaning efficiency.

[0051] In terms of structural fit, as the sliding member 22 slides axially along the insertion shaft 18, it drives the hinge claw to unfold via the connecting rod 28, causing the hinge arm 23 to rotate radially. Its end is integrally connected to the inner side of the support plate 25 via the fixing head 24, thereby causing the support plate 25 to fold outward in an "umbrella-like" structure. During the rotation process, the support plate 25 gradually expands the elastic cotton 26 sleeved on its surface, causing the elastic cotton to open outward from its initial contracted state, ultimately forming a cleaning cavity that fits and surrounds the chopsticks, achieving bidirectional friction cleaning in conjunction with the fixing cotton 115.

[0052] The use of two sets of independent but symmetrical fixing parts 21 and sliding parts 22 not only simplifies the manufacturing and assembly path of the hinge arm 23 and reduces the stress burden on the insert shaft 18, but also gives the entire internal support mechanism good structural self-balancing ability. When the sliding part 22 is displaced by the same distance relative to the insert shaft 18, it can synchronously ensure that each support piece 25 has at least two support points, ensuring the stability and consistency of the outward expansion of the elastic cotton 26, and achieving a synchronous and approximately parallel movement. In high-frequency repeated use, it is not easy to have structural deformation, jamming or breakage problems, significantly improving the service life and safety performance of the whole machine.

[0053] Specifically, a spring 27 is assembled between adjacent fixed members 21 and sliding members 22; Spring 27 is an axial compression spring, with one end fixedly connected to the inner wall of the fixing member 21 and the other end abutting against the lower surface of the sliding member 22. It is located in the gap area between the fixing member 21 and the sliding member 22 along the axial direction of the insertion shaft 18. When not subjected to external force, spring 27 always remains in a naturally extended state, applying a continuous upward elastic force to the sliding member 22, causing the sliding member to return to its initial position, thereby driving the support plate 25 to retract and completing the automatic reset of the cleaning mechanism.

[0054] When the user presses down on the top of the insert shaft 18 using the pressure rod 29 to trigger the cleaning process, the sliding member 22 is forced to slide downward under the action of the pressure rod linkage structure, compressing the spring 27 to store energy. The support plate 25 unfolds synchronously by relying on the hinge arm 23, and expands the elastic cotton 26. After cleaning is completed, the pressure rod 29 is released, and the spring 27 quickly rebounds after losing external pressure, causing the sliding member 22 to move upward. This, in conjunction with the hinge arm 23, causes the support plate 25 to return to its closed position, and the elastic cotton 26 automatically rebounds to press tightly against the outer surface of the insert shaft 18, realizing the passive retraction and reset function of the cleaning mechanism.

[0055] This design simplifies the user's operation process, eliminating the need for electronically controlled actuators to assist in return. The mechanism can be restored solely by the mechanical prestress of spring 27, improving ease of use and structural stability. It is particularly suitable for the frequent opening and closing needs in home settings. At the same time, the spring design also has a certain shock absorption and cushioning effect, reducing the mechanical impact that may be generated during the extension and retraction of the inner support mechanism, and improving the overall durability of the machine.

[0056] Specifically, the support piece 25 has protruding strips extending outward at both ends, and the ends of the elastic cotton 26 are engaged with the inside of the protruding strips; The support piece 25 is a flexible reinforced sheet structure, arranged in an arc-shaped strip around the circumference of the insert shaft 18. Symmetrically arranged at both ends are radially extending protruding strips that can stably engage with the edges of the elastic cotton 26. The elastic cotton 26 has a pre-set annular limiting opening and an elastic groove at its end. When the support piece 25 unfolds, the engaging edge of the elastic cotton 26 tightly adheres to the protruding strip under the elastic force of the groove, thus achieving controlled unfolding and preventing dislocation.

[0057] The design of this structure allows the elastic cotton 26 to automatically expand as the support plate 25 unfolds in an umbrella shape, and it will not shift or flip during the rotational washing process due to high-speed movement or friction from chopsticks, significantly improving the stability and fit of the washing contact surface. The protruding strips also act as radial inward stop points when the elastic cotton is in the retracted state, preventing the elastic cotton from collapsing excessively inward when the washing mechanism is not in operation.

[0058] Furthermore, the protruding strip and support piece 25 are integrally injection molded or insert-molded to ensure overall structural rigidity, while providing good radial support when the elastic cotton is stretched. Through these features, the cleaning mechanism can better adapt to chopsticks of different materials and sizes during use, improving the versatility of the structure and the uniformity of cleaning.

[0059] Specifically, the top of the outer fixed cylinder 111 is fitted with a connecting cover 110, a guide tube is provided at the center of the connecting cover 110, a pressure rod 29 is fitted inside the guide tube, and a round hole is provided at the center of the pressure rod 29. The connecting cover 110 is a circular snap-on structure. Its lower edge is locked to the top opening of the outer fixing cylinder 111 by a snap-lock ring, making installation convenient and ensuring a reliable seal. The guide tube in the middle of the connecting cover 110 is a hollow tubular structure extending vertically downwards. Its axis is concentric with the insertion shaft 18, used to guide the pressure rod 29 in a straight line during its up-and-down movement. This guide structure effectively prevents the pressure rod from lateral swaying or shifting, ensuring stable and reliable pressing action. The top of the connecting cover 110 is also equipped with a water inlet pipe, or a universal open-hole structure, for easy connection to a kitchen faucet for water injection during use. Initially, users can inject an appropriate amount of water and detergent into the cleaning chamber to complete the main cleaning. Then, turn on the faucet to continuously inject clean water from the inlet pipe or opening to rinse the chopsticks, removing residual detergent and impurities, making the cleaning process more complete and hygienic. This design eliminates the need for a separate drain interface, simplifying the structure and adapting to everyday household habits. To prevent water splashing and guiding errors, annular sealing rings or waterproof baffles can be provided between the connecting cover 110 and the guide tube, and between the guide tube and the pressure rod, respectively, to prevent external liquids or steam from seeping into the equipment through the gap of the pressure rod, thereby ensuring the integrity of the sealing structure above the cleaning chamber and extending the service life of the electrical control part.

[0060] The pressure rod 29 is a slender rod that can slide up and down. To ensure that the pressure rod can completely cover the downward stroke of the top of the insertion shaft 18 during the pressing process, the axial depth of the circular hole in its middle is preset to create sufficient insertion space when the insertion shaft 18 is displaced, thereby avoiding insufficient stroke or interference jamming problems, and ensuring that the entire starting process is smooth and reliable. One end of the pressure rod extends out of the guide tube, and the other end extends into the cleaning structure and connects with the top of the sliding member 22. To avoid direct friction between the pressure rod 29 and the rotating sliding member 22 during operation, which could lead to obstruction or wear; Preferably, a friction-reducing structure is provided at the bottom end of the pressure rod 29. This structure can be in the form of an embedded ball bearing, with a hemispherical recess at the lower end of the pressure rod and a metal ball bearing embedded therein. When pressed down, the ball bearing rolls with the rotation of the sliding component, thereby avoiding strong contact friction between the static pressure component and the rotating component. Alternatively, a low-friction pad made of polytetrafluoroethylene can be installed at the end of the pressure rod to reduce rotational friction through the sliding properties of the material itself. Furthermore, by setting an elastic buffer, such as an elastic isolation cap or a small sliding contact structure, the lower end of the pressure rod can generate a certain amount of clearance or sliding ability under stress, thereby alleviating the frictional pressure at the rotating interface.

[0061] The above structural solutions can be flexibly selected based on manufacturing costs and structural compactness. All of them can effectively extend the service life of components and improve operational smoothness without changing the upper and lower guiding function of the pressure rod.

[0062] Specifically, the cleaning machine is equipped with a start-up control system, which includes a control trigger module, a signal response module, and a power supply execution module. The control trigger module is triggered by the downward pressing action of the pressure rod 29 and is located on the non-rotating component. The signal response module and the control trigger module work together to output control signals. After receiving the control signal, the power supply execution module drives motor 12 to start the cleaning process.

[0063] In terms of further optimizing the control method, this utility model can also adopt a variety of feasible low-voltage start-up schemes in combination with different product models or usage scenarios to improve the overall operational flexibility and safety. In addition to the basic pressure rod trigger structure, a wireless transmission module can also be integrated inside the pressure rod 29 to drive the receiving circuit in the base to start the motor 12 through a short-range low-power signal, eliminating any physical contact or wire connection, which is suitable for versions with high integration and high waterproof requirements.

[0064] Another form is as follows: at the end of the pressing process of the pressure rod 29, a low-voltage flexible wire is led out through the space between its body and the base. The wire is embedded between the guide tube and the pressure rod connection structure. When the pressure rod is pressed down to the designated position, the flexible contact or button is triggered to complete the start signal closure. The structure wiring is simple and the control path is clear, which is suitable for mass plastic injection molding integrated manufacturing.

[0065] In addition, a pressure sensor can be installed between the spring 27 and the fixing member 21. The displacement pressure generated when the sliding member 22 compresses the spring downwards can be used to realize the function of automatically sensing and energizing after the cleaning load reaches the set value; or a manual speed control switch can be directly installed on the power supply wire of the motor 12, so that the user can manually set the cleaning intensity and duration before pressing the cap, which is suitable for versions that require a stronger sense of manual control.

[0066] In terms of structure, the connection between the cover 110 and the outer fixing cylinder 111 can also be designed as a flip-up hinge structure. When the user completes the action of closing or pressing the cover, the pressure rod 29 is guided into the guide tube, automatically triggering the start-up logic. At this time, the wire can pass through or be arranged in the flip-up opening along the hinge axis, ensuring the concealment of the control circuit and structural coordination.

[0067] Furthermore, the outer wall of the outer fixed cylinder 111 can also serve as a start-up sensing area, designed as a grip-type start-up unit. For example, a grip force sensor or a spring-loaded rotary switch can be embedded in the normally gripped position. When the user naturally grips the cleaning device during operation, the motor start signal is triggered. This design fully conforms to ergonomic principles, requires no extra movements, provides an excellent user experience, and is especially suitable for the elderly and children.

[0068] In the specific implementation of this utility model, in order to achieve a compact, responsive, and adaptable start-up control logic, a start-up control system consisting of three parts is preferably set up, including a control trigger module, a signal response module, and a power supply execution module. The three parts are linked and coordinated to complete the cleaning start-up process after user operation.

[0069] The control trigger module is used to receive direct user actions, preferably using the downward pressing action of the pressure rod 29 as the trigger input. This module can be installed on the inner wall of the connecting cover 110, the outer shell of the guide tube, the body of the pressure rod 29, or at the lower limit position that mates with the pressure rod. Specific forms include: A miniature switch is installed at the bottom of the guide tube or the lower edge of the connecting cover, and is triggered when the end of the lever is pressed down to the desired position. The Hall magnetic induction unit (Hall Sensor + permanent magnet) has a magnet embedded in the bottom of the pressure rod 29, and the corresponding sensor is set in the connecting cover 110 or the guide tube shell; A soft-touch sensor is located at the contact surface between the end of the pressure rod and the stationary structure. A mechanical insertion-type limiting structure (such as a flip-top contact) sets the connecting cover 110 as a hinged structure. When the cover is closed, it pushes the pressure rod into the guide tube, triggering the internal limit switch. The gripping pressure pad is located on the outer wall of the outer fixed cylinder 111 in the area where the user is normally gripping the device. It is activated when the user supports the device. The signal response module is used to generate control signals based on the actions of the aforementioned control trigger module. It can be located inside the base 11, in the middle of the guide tube, on the outer edge of the motor cavity, or in the connecting cover housing. Optional structures include: General-purpose open circuit micro switch contacts; Hall sensor drive circuit (used with a magnet); Capacitive Touch Switch Module. The wireless receiver module (RF Receiver Module) corresponds to the low-power wireless transmitter (such as a 433MHz wireless signal chip) embedded inside the pressure bar 29. A pressure sensor is embedded between the spring 27 and the fixing member 21, and forms a closed signal through pressure feedback; A rotary switch or a linear slide switch can be placed in an easily accessible location on the device housing; The power supply module, as the electric drive part of the system, mainly includes power supply lines, a motor control chip, motor 12, and a speed control unit. Its installation location is typically within the cavity of the base 11. Optional components are as follows: DC power input interface (DC Power Port), external adapter power supply; A microcontroller board (MCU board) is used for signal processing and delay logic; An optional speed control knob (Speed ​​Potentiometer) is available for controlling the motor speed (12 RPM) and is located on the edge of the base or connecting cover. Relay or MOSFET switch control unit is used for power on / off control; A timing chip or shutdown delay module (such as the NE555 timer) is used to set the single cleaning cycle; Waterproof power leads and shielding structure pass through the connection between the connector cover and the base; The coordination logic between the above modules is as follows: The user triggers the displacement or sensing structure in the control trigger module by pressing down the lever 29, closing the lid, or gripping the outer shell. The signal response module outputs a start signal based on this action. Upon receiving this signal, the power supply execution module powers on the motor 12, causing the insertion shaft 18 to rotate, thus completing the chopsticks cleaning process. Each module is distributed on the non-rotating parts and has no electrical connection to the rotating structure, ensuring system safety, a reasonable structure, good manufacturing adaptability, and convenient maintenance.

[0070] Specifically, the bottom section of the insert shaft 18 is provided with a socket 19, which is engaged with the coupling 15. The connector 19 is an axially positioned non-circular groove structure, which can be rectangular, square, or cross-shaped, and its cross-section perfectly matches the shape of the output plug of the coupling 15. This non-circular mating structure has a stronger torque transmission capability during rotational transmission and can effectively prevent slippage or freewheeling, making it particularly suitable for cleaning operations under frequent start-stop and high load conditions.

[0071] The coupling 15 is driven to rotate by the output shaft of the motor 12. Its plug end can be directly inserted into the non-circular socket 19 at the bottom of the insert shaft 18 to achieve synchronous output of rotational power. This structure is not only easy to assemble, but also ensures coaxial positioning accuracy through structural limiting, thereby improving the overall transmission efficiency and service life of the machine.

[0072] Furthermore, to prevent the plug from coming loose, a snap-fit ​​groove or radial limiting hole can be provided between the socket 19 and the coupling 15, with axial stop provided by a snap ring, locking pin, or limiting screw. When maintenance or replacement of the plug assembly is required, quick disassembly and assembly can be completed simply by loosening the limiting piece, without damaging the connection structure between the motor and the coupling.

[0073] This design enables the replacement and modularity of the transmission unit, while ensuring rotational synchronization and anti-slip stability through non-circular connectors. It is an important basic structure to ensure the safe and efficient operation of the cleaning mechanism.

[0074] The snap-fit ​​cylinder 114 and the fixing ring 113 are detachable, so that the fixing cotton 115 installed on the inner wall of the snap-fit ​​cylinder 114 can be replaced. The fixing cotton 115 can be installed on the inner wall of the snap-fit ​​cylinder 114 by snap-fitting, elastic pressing, nesting and bonding or threaded connection.

[0075] For easy daily replacement and cleaning, the snap-fit ​​tube 114 and the retaining ring 113 are detachable. The snap-fit ​​tube 114 can be quickly disassembled from the retaining ring via rotating the snap-fit ​​claw 116 or a plug-in connection, allowing the user to easily remove it to clean or replace the retaining cotton 115 inside the tube. The retaining cotton 115 is preferably made of a flexible absorbent or highly elastic material and can be fixed to the inner wall of the snap-fit ​​tube 114 in various ways, such as directly embedding it into a preset limiting groove, pressing it with an elastic fitting structure, fixing it with adhesive strips, or having an internal threaded ring on the inner wall of the snap-fit ​​tube to achieve screw-in cotton pad fixation. All of the above methods can achieve quick installation and removal and a stable fit, ensuring that the cotton pad will not shift or fall off during cleaning.

[0076] In practical use, the user first places the entire household kitchen chopsticks washing machine of this utility model inside the kitchen sink, preferably in the center of the bottom of the sink, so that the base 11 is stably attached to the bottom of the sink. The equipment has a compact structure and is compatible with common household sink sizes. After placement, the outer fixing cylinder 111 is kept vertically upward to ensure the normal operation of the internal cleaning mechanism.

[0077] The user then opens the connecting cover 110, revealing the cleaning chamber located inside the outer fixing cylinder 111, and injects an appropriate amount of water into the chamber, adding a small amount of kitchen detergent as needed. The user inserts several chopsticks to be cleaned into the chamber, accurately placing them between the elastic cotton 26 and the fixing cotton 115, with the insertion depth above the positioning ring 117 to ensure that the chopsticks remain vertically positioned and fully contact the cleaning structure during rotation. At this time, the elastic cotton 26, in its unfurled state, provides a certain initial adhesive wrapping force, forming a stable pre-assembled state.

[0078] After loading, the user closes the connecting cover 110, inserts the pressure rod 29 along the guide tube, and moves it to the ready-to-start position. The equipment is preferably equipped with a rotary power switch, which is installed on the outer wall of the outer fixed cylinder 111 or the side of the base 11. After the user rotates the switch to the "start" position, the control system responds, the motor 12 is powered on and runs, driving the coupling 15 and the insert shaft 18 to rotate.

[0079] During the rotation of the insert shaft 18, the sliding member 22 is driven to move axially, and the support plate 25 is unfolded through the connecting rod 28 and the hinge arm 23. The support plate causes the elastic cotton 26 to be stretched outward, forming a wrapping cleaning space. The chopsticks rotate synchronously under the drive of the insert shaft, forming a relative friction surface with the elastic cotton 26 and the fixed cotton 115. Combined with the action of detergent and water flow, the surface oil and residue are effectively removed.

[0080] After the cleaning process is complete, the user rotates the control knob to turn off the device and opens the connecting cover 110 to remove the cleaned chopsticks. If further rinsing is required, the user can directly turn on the tap and inject clean water into the device from the inlet or open position on the top of the connecting cover to rinse away residual foam and impurities. The wastewater will then naturally drain into the pool, making the cleaning process clean and efficient.

[0081] After use, it is recommended that users keep the connection cover 110 open to allow the inside of the device to air dry naturally, or wipe the inner wall of the cavity with a dry cloth to keep it clean and extend the product's service life.
